Researchers identify a cell type that limits stroke damage
A research team including Serge Rivest of University Laval's Faculty of Medicine has demonstrated the existence of a type of cells that limits brain damage after a stroke. The study was recently published in the online version of Nature Medicine. view more (2009-01-28)
Nerve prosthesis developed in Ume'å
The first clinical study ever with a new type of nerve prosthesis has been launched at Northern Sweden University Hospital. It is being carried out by a research team from Ume'å University under the leadership of Professors Jan-Olof Kellerth and Mikael Wiberg. The team, at the Department of Integrative Medical Biology and the Department of... view more... (2003-11-11)
Jefferson scientists discover a key protein regulator of inflammation and cell death
Reporting in the journal Nature, researchers led by Emad Alnemri, Ph.D., professor of Biochemistry and Molecular Biology in the Kimmel Cancer Center at Jefferson, discovered a key protein component involved in inflammation. view more (2009-01-23)
Cord blood cells may widen treatment window for stroke
Researchers at the University of South Florida found that human umbilical cord blood cells administered to rats two days following a stroke greatly curbed the brain's inflammatory response, reducing the size of the stroke and resulting in greatly improved recovery. view more (2005-11-14)
Adult human neural stem cell therapy successful in treating spinal cord injury
Researchers at the UC Irvine Reeve-Irvine Research Center have used adult human neural stem cells to successfully regenerate damaged spinal cord tissue and improve mobility in mice. view more (2005-09-20)
New role for gene that counteracts formation of tumors
The researchers, connected to Ghent University, have discovered the function of an important mediator involved in suppressing the development of tumors. view more (2005-08-26)
Sun-damaged skin does not improve with estrogen treatments
Treating the skin with estrogen can stimulate collagen production-which improves the appearance of the skin-in areas not typically exposed to the sun, according to new research from the University of Michigan Health System. view more (2008-09-16)
New research targets treatment for dementia and brain injuries
Queensland Brain Institute (QBI) researchers have identified a process that could lead to development of repair mechanisms for people suffering from dementia and acquired brain injury. view more (2005-11-29)
Spinal cord repair: pilot trials "within sight"
When the brain and spinal cord are injured, the damage is permanent, because the tissues cannot repair themselves in the way that bone and skin can. Writing in the June Journal of the Royal Society of Medicine, Dr Geoffrey Raisman describes encouraging results from a new approach to the problem, which he believes will make it possible to plan a... view more...

Pittsburgh scientists identify human source of stem cells with potential to repair muscle
For the first time, scientists at Children's Hospital of Pittsburgh of UPMC have discovered a unique population of adult stem cells derived from human muscle that could be used to treat muscle injuries and diseases such as heart attack and muscular dystrophy. view more (2007-09-05)
Biologists discover bacterial defense mechanism against aggressive oxygen
Bacteria possess an ingenious mechanism for preventing oxygen from harming the building blocks of the cell. view more (2009-11-23)
Is sleep 'hard-wired' into the brain?
Falling asleep is usually thought of as something we can control ourselves as part of our behaviour patterns. In a new article in the December Journal of the Royal Society of Medicine, Dr Bidi Evans argues that waking and sleeping is actually controlled by a physical mechanism that is 'hard-wired' into the brain. She suggests that evidence from... view more... (2002-11-25)
Raising the alarm when DNA goes bad
Our genome is constantly under attack from things like UV light and toxins, which can damage or even break DNA strands and ultimately lead to cancer and other diseases. view more (2009-08-14)
Study shows isolation of stem cells may lead to a treatment for hearing loss
Have you ever walked by someone listening to their i-Pod loud enough for you recognize the song? Studies have shown noise-induced hearing loss is going to become the next big epidemic affecting our younger generation though the effects won't show until it is too late to treat. view more (2007-04-06)
Enhanced DNA-repair mechanism can cause breast cancer
Although defects in the "breast cancer gene," BRCA1, have been known for years to increase the risk for breast cancer, exactly how it can lead to tumor growth has remained a mystery. view more (2007-10-15)
Cancer-causing protein may heal damaged spinal cord and brain cells
Cancer researchers at Columbia University Medical Center have found that a protein known for driving the growth of cancer also plays a surprising role in restoring the ability of neurons to regenerate, making it an important target for addressing spinal cord damage or neurological diseases like Alzheimer's. view more (2006-06-29)
Weizmann scientists discover a new line of communication between nervous system cells
In a host of neurological diseases, including multiple sclerosis (MS) and several neuropathies, the protective covering surrounding the nerves - an insulating material called myelin - is damaged. view more (2007-06-27)
MIT identifies cells for spinal-cord repair
A researcher at MIT's Picower Institute for Learning and Memory has pinpointed stem cells within the spinal cord that, if persuaded to differentiate into more healing cells and fewer scarring cells following an injury, may lead to a new, non-surgical treatment for debilitating spinal-cord injuries. view more (2008-07-22)
Dampened hopes for transplanting bone marrow stem cells in heart attacks
There is little, if any, evidence that adult stem cells can build other cells in an adult organism than those formed in the organs they themselves come from. At any rate, blood stem cells do not convert to heart muscle cells in a damaged heart, which was previously hoped. This has been shown by a research team from the Stem Cell Center at Lund... view more... (2004-05-06)
Cardiac cell transplant studies show promise in cardiac tissue repair
Two studies published in the current issue of CELL TRANSPLANTATION (17:6) examine the efficacy of transplanting bone marrow cells (BMCs) for the repair of heart tissue. view more (2008-09-04)
